One late afternoon in early September, Jilly sees something. It looks like it s raining black pepper from a clear blue sky. Then the black rain becomes a wispy mist. And then a spooky orange cloud. What can it be? Jilly and Mom set out to identify the mysterious orange cloud. The closer they get, the more Jilly s guesses change. Gradually, the hidden world of nature opens to mother and daughter. This imaginative description of Monarch butterfly migration reminds us that a loving parent can empower a child to discover the mysteries of the natural world and to enjoy that discovery again and again. Because when you re making a memory, you want it to last as long as possible.
